Selflocking of spring hangers

Selflocking of spring hangers

Selflocking of spring hangers

(OP)
In our plant we had number of cases where spring hanger locking nuts have moved into "locked position" due to piping vibration - nuts tend to slide down. That resulted in spring hanger casing damages and temporarily increased piping loads. To minimize such occurrences I'm thinking we could replace existing *plain nuts* with those with plastic inserts.

Does anyone have an opinion on the effectiveness of the proposed or an alternate suggestion? Would appreciate some help for this practical issue.
